Notes on Carex—xl 
KENNETH KENT MACKENZIE 
CALIFORNIAN REPRESENTATIVES OF THE OVALES 
During the past few years I have been favored with oppor- 
tunities to examine a very considerable percentage of all collections 
of Carex heretofore made in the state of California. With the 
exception of specimens referable to the Ovales, these collections 
- contain comparatively few plants not readily referable to species 
heretofore described. In the case of the Ovales, however, it has 
turned out that there are a number of. undescribed species in 
California. In fact, most of the Californian collections in the 
group belong to undescribed species. 
This situation arises from the fact that attempts have been 
made in the past to refer the Californian Ovales to species in the 
group found in the eastern portion of the United States or in the 
Rocky Mountain region. Similar attempts were made at one 
time with a number of species belonging to other groups of Carices, 
but these have gradually been corrected. In the case of the 
Ovales little has been done in this direction, and as a result a 
number of species are attributed to California which do not occur 
within a great many miles of that state. 
The fact is that the species of Carex found in California are 
very largely peculiar to that state, and this is just as true in the 
case of the Ovales as in other groups. 
The collections examined for the purpose of this paper were 
those of the University of California (abbreviated “Cal.’’), Leland
